81. SET AUX INPUT LEVELSIf you use any device (mp3 player, sat radio receiver, etc) that uses a headphone out jack as input to the AUX IN, set the volume on that device to approx. 80-90% of full volume. Adjust the AUX IN level setting in the headunit to around 60-80% of full volume.

From the music control section in the headunit, select TONE -> VOLUME SETTINGS -> AUX INPUT LEVEL and set the level.

82. CONFIRM SPEAKER CONNECTIONS & SETTINGSIn the headunit, turn the Balance control to fade full Left. Start-ing with a 20Hz tone, play each higher frequency up to about 4kHz. You should hear only the subwoofer first, then at ~50Hz you’ll transition to the underseat woofer, at ~150Hz to the mid-range, and the tweeter at ~2.5kHz. You should hear each speaker on the left, in the correct order. You may get some sound from the right, but it should be low level. Fade Balance full Right and repeat the process. When complete, center Balance & Fade.

83. ROCK. AND ROLL.Reinstall any remainingtrim panels, seats, etc, in the reverse order they were removed.

That’s it! You should be ready to rock and roll. If you aren’t seriously impressed by the sound, something is wrong. Trust us on this. It should be clean, clear, and balanced. If it isn’t, revisit the steps above or reach out to us for support at 646-926-0011 or email us at support@integralaudio.com.

Verify that each speaker is playing correctly.

NOTE

NOTE

S• AMPLIFIER TURN-ON: You will notice that the amplifier turns on before the head unit, and remains on

after the head unit is off. This is normal. The sound output system needs to be energized to play your door chimes, parking distance control sounds, bluetooth, etc. The amp will turn on from the moment the doors are unlocked or opened, and remain on from between 30 seconds and as much as 20 minutes after the car is locked. Again, this is perfectly normal. The idle current on the ARC amp is virtually zero and will not cause any issues with battery drain.

• SIGNAL SOURCE QUALITY: A poor quality signal will always sound poor no matter how good an audio system is. If you are using MP3s or home-burned CDs it is critical that you understand the limitations and impacts of digital compression methods. MP3s at less than 256kbps will have noticeable loss of quality. Satellite radio is also compressed and will have similar quality issues. Non-commercially ob-tained music (especially downloaded via P2P file-sharing) recordings are often re-mixed by third parties and will have been compressed in an unknown and uncontrolled manner. If you want good quality sound, use only commercially obtained CDs or MP3s compressed at 256kbps or 320kbps.

• FACTORY RADIO SETTINGS: Please note that the settings (Bass, Treble, Fade, Balance, AUX input level, etc.) are stored to each Key FOB & are specific to the Source (Radio, CD, AUX) for many vehicles. You will need to edit and save the settings for each source and each FOB to have consistent sound.

• PLEASE LISTEN RESPONSIBLY: Your new Integral Audio system is capable of delivering Sound Pressure Levels that can damage your hearing. It also delivers very clean, low-distortion sound reproduction. Because distortion sounds bad to your ears, and low-distortion sounds good, you are much more likely to listen at high levels with your new system. Please exercise caution - we want you to enjoy a lifetime of great sound!

Having Trouble? The best thing to do is contact us at support@integralaudio.com or via the phone number listed on the receipt that was emailed to you. We’ll get you fixed up ASAP!
